Bug

Output of python -c "import pydantic.utils; print(pydantic.utils.version_info())":

             pydantic version: 1.8.1
            pydantic compiled: True
                 install path: /home/musttu/.pyenv/versions/3.9.4/envs/py39/lib/python3.9/site-packages/pydantic
               python version: 3.9.4 (default, May  3 2021, 13:52:18)  [GCC 9.3.0]

     optional deps. installed: ['typing-extensions']

With mypy.ini:

[mypy]
plugins = pydantic.mypy

import pydantic

class Foo(pydantic.BaseSettings):
    pass

Foo.construct()

$ mypy models.py
models.py:6: error: Missing named argument "__config__" for "construct" of "Foo"
Found 1 error in 1 file (checked 1 source file)

Only occurs if pydntic's mypy plugin is enabled. Why is that?

I'm also hitting this on 1.10.12, mypy 1.3, what is the recommended solution? upgrading pydantic?

[jordanearnest1]

Yes, what is the solution? Hitting this on Pydantic 2.3.0, mypy 1.5.0.

Same issue here, pydantic 1.10.6, mypy>=1.0.0.
